What headlamp do you use?

I have two e-lites and the switch on the first one did jam a little with the super fine sand while doing a Hayduke section hike but works fine now and the second one has never had issues.  I trust it as my main light (for everything but night hiking).  I do bring a small button light for back up.

I was using a Photon button light a little, but when it got really cold it wouldn’t work.  I think it was too cold for the electronics.

Now I use a regular button light as a backup.  Internally, there’s a spring that when I push on the button, it pushes the spring to touch one side of the battery and the light comes on.  I have to hold the button down to keep the light on.  No dimming modes or anything.  Simplicity = reliability.

Jerry,

I think the Photon light did not work in the cold B/C it did not have a lithium battery but likely some kind of alkaline battery.

I feel carrying only a button light is taking SUL too far. My very light UL light is a tiny Princenton Tech Scout head light that sadly is no longer in production. It uses 4 coin batteries and has 3 power levels. The batteries seem to last at least two years of 3 season use.

Black Diamond Spot for 5 years now.

I agree, button light isn’t enough, okay for backup

Photon has a 2016 battery which is lithium, but there’s something about it that made it not work when cold.  Too bad because you don’t have to hold the button down and you can dim it

That’s weird, on the inside of the battery cover is a secret message “freedom of religion”

“freedom of religion”
I sometimes wonder whether that includes the worship of Cthulhu.

Cheers

Night core NU25 with Shockcord headband or a Streamlight Bandit. Both are around an ounce, rechargeable, and work well.
